Bussmann LPJ-40SP 600V AC/300V DC, 40A, Dual Element, Time-Delay Fuse

This time-delay fuse from Bussmann has been designed with an optional open fuse indication on select ratings (see data sheets).

Other features include the separate overload and short-circuit elements, providing time delay for sizing of high inrush loads linked with Class J current limitation, while selective coordination ratio of 2:1 (within low-peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit.

Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer.

• Minimum 10sec time delay at 500% overload
• Minimises needless fuse openings due to temporary overloads and transient surges
• Provides back-up protection against motor burnout (from overload or single-phasing)
• High interrupting rating to safely interrupt overcurrents up to 300,000A
• High degree of current limitation due to the fast speed-of response to short-circuits
• Faster response to damaging short-circuit currents
• Reduces let-through thermal and magnetic forces
• Length: 60.5mm
• Diameter: 26.9mm
• Nominal current: 40A
• Nominal voltage: 600V AC
